Dear gPPI experts,

I have been trying to apply gPPI analysis to fMRI data processed by freesurfer and had two questions. It'd extremely helpful if you could give me your advice.

First, I was wondering how to make VOI files for gPPI based on .label and aseq.mgz files made by freesurfer. Is there any script for this purpose included in gPPI? Alternatively, is it possible to make such script by myself by using freesurfer-matlab interface scripts (like MRIread.m)?

Second, is there any script or pipeline to transform results obtained by the gPPI analysis to a freesurfer format so that I can perform statistics on freesurfer? I wondered if con.img made by gPPI corresponds to ces.nii on freesurfer. But if it is correct, I am not sure how to transform con.img to ces.nii.

Thank you very much for your help in advance!

Best,
Kaz
